HYDROCARBON-VAPORIZING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 766,513, dated August 2, 1904.

Application filed May 15, 1902. Serial No. 107.414. (N0 model.)

To all whom it may concern.-

Be it known that I, ALBERT S. NEwBY, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in I-Iydocarbon-Vaporizing Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an apparatus for use in generating gas from hydrocarbon oils, such as gasolene, from which the gas may be conducted to any desirable point of delivery for consumption.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claim.

Figure I is a front perspective view of my apparatus. Fig. II isavertical section taken on line II II, Fig. I, through the safety appliance of the apparatus. Fig. III is a vertical section taken centrally through the apparatus. Fig. IV is an enlarged horizontal section taken on line IV IV, Fig. III. Fig. V is a cross-section taken on line V V, Fig. IV. Fig. VI is a horizontal section taken on line VI VI, Fig. III.

1 designates the base of the apparatus, on which the outer shell 2 is supported by legs 3.

I designates an oil-tank located in the shell 2, completely housed within said shell, so that in the event of leakage from said tank the oil will only escape into the shell. The shell 2 also provides a protection for the oil-tank that prevents injury to the tank from external sources and obviates all liability of the tank being injured to result in the escape of oil therefrom. This oil-tank 4: does not lill the space within the shell 2, but is so mounted therein as to provide a chamber 5 about the tank, into which air may be introduced under pressure. Air is introduced into said chamber 5 through a pipe 6, that is provided with a valve 7, having a nipple 8, to which a suitable air-pump may be applied. Air that is introduced into said chamber is adapted to pass therefrom into the oil-tank 4 through a pipe-section 9, that is provided with an aperture 10, leading thereinto.

11 is an inlet-tube extending from the exterior of the shell 2 into said oil-tank 4, through which oil may be introduced into the tank, the tube being closed when the apparatus is in use by a cap 12.

13 designates a vapor-conducting pipe that passes through the shell 2 and oil-tank a and is provided with an orifice 1 1, through which communication is established into said pipe from the oil-tank above the oil-line for the entrance of vapor or the air saturated with the fumes of the oil in the tank. The pipe 13 is provided with a shut-off valve 15, by which the passage of vapor or impregnated air is controlled.

16 is a coupling fixed to and having communication with the upper end of the vaporconducting pipe 13, (see Fig. IV,) and 17 is a lighter-tube attached to said coupling and provided with a vapor-escape slot 18. In the lighter-tube is a filling 19, of wire-gauze or other suitable material, that prevents too rapid flow of vapor through the lighter-tube to the outlet therefrom. The lighter-tube is surrounded by a jacket 20, preferably of wire-gauze, through which the vapor passes for consumption in the initial starting of the 'apparatus to heat the generator that subseq uently converts the oil conducted thereto into gas.

21 designates an oil-conducting pipe leading through the shell 2 and oil-tank 4 and provided within said oil-tank, at the bottom thereof, with an upper inlet-orifice 22 and a lower orifice 23. The oil-conducting pipe 21 leads upwardly from the shell 2 and is equipped with a shut-off valve 24:, by which the flow of oil through said pipe may be controlled.

25 is a generator-tube connected to the upper end of the oil-conducting pipe and having its outer end closed by a cap 26, that may be removed for the purpose of permitting access to the interior of the generator-tube to clean such interior.

27 is a plug loosely fitted in the generatortube and provided with an annular groove 28, located in alinement with the oil-conducting pipe 21 to receive the oil that enters the generator-tube. (See Figs. III and IV.)

29 is a groove extending longitudinally of the plug 27 (see Figs. IV and V) and leading from the annular groove 28 to the inner end of the generator-tube chamber, through which the gas or vapor passes as it is converted from the oil within said generator.

30 designates a jet-head having communication With the chamber of the generatortube 25 through a duct 31, that is adapted to communicate with a duct 32 in the nipple 33 of said head. The passage of gas or vapor through said jet-head is controlled by a needle-valve 34, that is carried by a stem 35, provided with an operating-handle 36.

37 is a drip-cup mounted on the shell 2 beneath the jet-head.

38 designates a mixing-tube fitted to the nipple 33 of the jet-head and resting upon a shelf 39, that is fitted on the vapor-conducting pipe 13 and generator-tube 25. The mixing-tube 38 is provided with an air-inlet 40, through which air enters said tube from an air-box 41, that is mounted on the shelf 39. Air is admitted to the air-box 41 through an air-conducting pipe 42, that leads from any suitable point to said box and through which fresh air is constantly delivered to enter the mixing-tube 38 and mingle therein with the gas or vapor that escapes from the nipple of the jet-head 30. The mingled gas or vapor and air ready for use passes from the mixingtube 38 into a gas-conducting pipe 43, in which it is conveyed away from the generator for consumption.

45 is a burner located beneath the generator-tube 25 and contains an escape-slot 46, through which gas or vapor may pass to burn beneath the generator for the purpose of heating the generator to maintain the generation of gas or vapor therein after the initial generation from' the lighter 17. The burner 45 contains a filling 47, preferably of wire-gauze, through which the gas or vapor filters as it passes through the burner. The supply of gas or vapor for the burner 45 is delivered thereto through a pipe-leg 48, that leads to the burner from the gas-conducting pipe 43 and into which sufficient gas will constantly pass from said pipe to supply the burner.

49 is a valve that controls the passageof gas or vapor from the pipe-leg 48 to the burner.

50' designates a hood mounted on the shelf 39 and extending downwardly therefrom to inclose the generator and jet-tube of the apparatus.

51 is a fume-conveying pipe having its lower end seated in the shelf 39 and adapted to receive the fumes of the unconsumed vapors that may at any time exist within the hood 50. This pipe 51 leads to any desirable point, preferably to the exteriorof the building in which the generator is located.

52 designates a branch pipe connected to the gas-conducting pipe 43 and having communication withsaid pipe 43.

53 is a valve-housing mounted on the branch pipe 52 and surmounted by a branch pipe 54,

that leads to the air-pipe 42. In the valvehousing 53 is a check-valve 55, that'is seated upon the upper end of the branch pipe 52 and held thereto by a spring 56, that surrounds the valve-stem 57 This part of the apparatus is intended for service as a safety appliance in the event of the creation of abnormal pressure of gas in the gas-conducting pipe 43, upon the existence of which pressure is exerted against the check-valve to unseat it and permit the escape of gas through the valve-housing 53 into the branch pipe 54 and therefrom into the air-pipe 42, through which it is discharged.

58 is a blow-off pipe provided with a controlling-valve 59. This pipe is connected to,

the shell 2 at the location of the pipe-section 9 and is also connected to the air-pipe 42. When oil is to be introduced into the tank 4 to fill it, the air in the shell-chamber 5 and oil-tank is permitted to escape through the blow-off pipe into the air-pipe to remove the air-pressure from said chamber and oil-tank instead of permitting the air impregnated with oil-fumes to escape into the room occupied by the apparatus on the removal of the cap 12.

In the practical operation of the apparatus air is first introduced under pressure into the shell-chamber 5 and oil-tank by the application of a pump to the nipple 8, the valve 7 being opened to permit the passage of air therethrough. After obtaining the desired airpressure in the apparatus the valve 7 is closed. The valve 15 in the vapor-pipe 13 is then opened and the impregnated air in the oil-tank is forced under pressure through said pipe 13 and escapes through the lighter-tube 17 to be burned beside the generator-tube 25 to heat oil that passesto said generator-tube through the pipe 21 on the opening of the valve 24 for such passage. At this time the needle-valve 34 is seated in the jet-head 30. When the generator-tube has become sufficiently heated, the valve 15 is closed, thereby stopping the delivery to the lighter-tube. The needle-valve 34 is then unseated and the generated gas or vapor passes from the generator-tube through the jet-head 30 into the mixing-tube 38,where it mingles with the air passing thereto and passes threrefrom into the gas-conducting pipe 43. A portion of the gas entering the pipe 43 passes into the pipe-leg 48 and descends to the burner 45, at which it is ignited and burns beneath the generator to maintain heated condition of the generator throughout the operation of the apparatus to constantly generate the oil forced to the generator-tube under pressure from the oil-tank.

In order to provide for the removal of sediment from the oil-tank, I connect a section 60 of pipe to the lower end of the oil-pipe 21. This section of pipe leads to the exterior of the shell 2 and is closed by a cap 61, upon the removal of which the tank may be drained, the lower orifice 23 in the oil-pipe being situ- IIO valve in the pipe which connects the gas-conducting pipe With the air-supply pipe, unseating upon abnormal pressure in the gas-conducting pipe. to permit the escape of the surplus gas to the air-supply pipe.
